Final answer:
In the glycolysis process, a net total of 2 ATP and 2 NADH molecules are produced from one molecule of glucose. The correct answer to the question is C) 2 ATP + 2 NADH.
Step-by-step explanation:
The process of glycolysis results in the production of energy-carrying molecules from one glucose molecule. The net energy yield of glycolysis includes a total of 2 ATP and 2 NADH molecules. While glycolysis itself produces four ATP molecules, two are consumed during the process, making a net gain of only two. Additionally, glycolysis results in the formation of two NADH molecules. The answer to the student's question is therefore C) 2 ATP + 2 NADH.
It's critical to note that these NADH molecules carry high-energy electrons that will contribute to the production of more ATP in the mitochondria during the electron transport chain. This makes the NADH a valuable energy resource for the cell, even though the immediate ATP yield of glycolysis is modest.
